Application filed March 18, 1916. Serial No. 85,144.

To all whom it may concern:

Be it known that we, LAWRENCE E. Hornwhich the rails are adapted to be secured,

the means employed for supporting the top section being housed within the tie and being simple, durable and eflicient;

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a view partly in elevation and partly in longitudinal section of a tie embodying the present improvements, rails being shown secured thereon. Fig. 2 is a horizontal section. Fig. 3 is a section on line A E Fig. 1, said sec tion being on an enlarged scale. Fig. 4 is a perspective view of one of the supporting le vers used in the tie.

Referring to the figures by characters of reference 1 designates a box-like member constituting the base of the tie, the same be ing extended into an inverted box-like top member 2 capable of shifting upwardly and downwardly relative to the base. Bearing extensions 3 are provided within the base 1 and are engaged by trunnions 4 extending from levers 5 the long arms of which are formed with recessed ends 6 which straddle a stem 7. This stem projects through an opening 8 in the base 1 and is provided at its lower end with a head 9 adapted to reciprocate within a'housing 10 secured to and depending from the base 1. Springs 11 are arranged within the housing and about the stem 7, these springs bearing at one end against the base 1 and at their other ends against the head 9. The uppei nd of the stem is secured to a saddle 12 which strad dles the recessed ends of lei/ers 5. The outer or short arm of each lever has a transverse groove 13 forming a seat for a rib 14 depending from the top section 2. One'of these ribs is provided for each lever and the two ribs are located directly under the rails R supported by the tie.

Formed upon the cover section 2 are retaming flanges 15 which overhang transverse grooves 16 formed in the top of the section 2. In these grooves are seated wedging blocks 17 which are overhung by the flanges and have shoulders 18 designed to lap the inner base flanges of the rails R. The outer base flanges of the rails are adapt: ed to be secured in like manner by Wedging blocks 19 engaging flanges 20.

It will be understood that the springs 11, by bearing downwardly on the head 9, hold saddle 12 down on levers 5 so that they will yieldingly support the section 2 above section 1. When the tie is subjected to pressure, however, the ribs 14 will thrust downwardly upon the short arms of the levers and cause the long arms to pull upwardly through the saddle 12, stem 7- and head 9 against the springs; 11 whichwill operate as cushions and retard the descent of the top section. Thus it will be seen that while the tie is made entirely of metal, it will provide the necessary resiliency.

It will be noted that all of the working parts are housed where the operation thereof will not be interfered with.

\Vhat is claimed is:

1. A metallic railway tie including a boxlike member constituting the base of the tie, an inverted box-like member slidable upwardly and downwardly on the first mentioned member and constituting the top section of the tie, means for securing rails to retarding the downward movement of the outer end portions thereof, and depending portions up'oii the top section directly under the centers o ftthe rails for thrusting downwardly upcn ithe' out-er end portions of the levers.

2. A met? nonstituting the base section of like membe the tie, an 1 J rerted box-like member constituting the top section of the tie, said top section being slidable upwardly and downi e railway tie including a box- I \vardly upon the base section, means for fastening a rail to the top section. oppositely extending levers fulcrumed within the base section, said levers having outer short arms and inner long arms, means depending from the top section and directly under the centers of the supported rails for engaging anh thrusting do\\'n\\ardl upon the short arms of the respective levers, a'housing depending from the base section, a head slidably mounted in the housing, springs interposed between the head and the base section. a

stem extending from are dead, and means carried by the stein for engaging the long arms of the levers.

In testimony that we claim the foregoing as our own, we have hereto atfixed our signatures in the presence of two witnesses.
